Domain walls of \(4d\)  supersymmetric QFT's have been studied in [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}, [18]}, [19]}, [20]}, [21]}, [22]}, [23]}, [24]}. Acharya and Vafa [14]} proposed the \(3d\)  Topological Quantum Field Theory (TQFT) living on the \(k\) -wall of pure \(SU(N)\)  SYM. [22]} considered \(SU(N)\)  and \(Sp(N)\)  SQCD in the regime with number of flavors \(F\)  smaller than the dual Coxeter number \(h\) , \(F < h\) .
